5.2 magnum GT35 to S475

It’s just a theory I have, and I could be wrong…. But I almost wonder if 5.2s have more boost pressure capability before blowing head gaskets than 5.9s due to the increased deck area from the smaller bore. Kinda like 4.8 and 5.3 is the “golden child” of sbe ls stuff. Smaller bore than ls1 6.0 etc so the cylinder head can clamp better. Maybe I’m wrong and it’s just a coincidence.

Interesting theory, but I can’t say I’m with ya. The difference between a 5.9 and a 5.2 is .09 and that ain’t significant when it comes to clamp load. I use studs and cometics so I dont have head gasket problems. And BTW I just gave Richard Holdener a 6.0 LS that I plucked from a junk van and watched it make 850 on very low boost. I’ve personally made 1200 with one and I know Richard has made 1543 with one. If you offered me a 4.8, 5.3, or a 6.0 all for the same price there is no world where I’d take anything but the 6.0.
